My old eyes like the visibility of vellum. Vellum also comes in pound weights and is not inexpensive. News print paper can be purchased by the ream from Office Max and Staples (look for 10lb weight). I don't know if reams of newsprint can be purchased at FedEx/Kinkos. Have you tried paper supply companies? In the Phoenix area we have PaperPlus. At the store locations you can buy paper by the ream vs the case.
